BURNER.

Application led May 12,

Be it known that l, SAMUEL lVinsoN Monnow` a citizen of the United States, resident of llaltii'nore, lilaryland, have invented certain new and useful improvements in Burners, of which the following is a speci iication.

This invention relates to a burner for use in cook stoves or heating stoves for burningoil as a fuel and it consists in the features and construction and arrangement of parts hereinafter described and particularly pointed out in the claims;

ln the accompanying,-drawings Figure 1 is a part vertical section and Yation of the burner.

Fig. 2 is a plan view of a portion of the distributor plate.

Fig. 3 is a plan view of the burner.

Fig. l is a view of the combined fuel and water tank, connected up with the burner in a stove.

ln these drawings 1 indicates a base member having seats at 2 for the hollow arms or pipes 3 for conveying air vto the point of combustion, these arms or pipes merging into a downwardly 4directed flared outlet portion at Ll. The base member 1 is mounted in the stove to form a horizontal partition between a lower chamber to which air is f recly supplied and an upper chamber formrThe oil which may be kerosene,ris delivered through a pipe 5 which connects with the central conduit or space 6v extending; vertically through ay distributer plate 7. 'l his plate has a depending boss at 8 which is screw threaded onto the upper end of the oil supply pipe and a shoulder le of the base member 1. rhe distributer plate has a central conical portion 10 and a dishcd rim portion 10. .At the upper portion of the conical center a flange 11 is formed extending in circular form around the central opening 6 series of notches or openings 1Q 4regularly disposed about the flangeso that the oil delivered through the central opening 6 may flow from the apex of the cone laterally and downwardly along the inclined surface and through the various notches 12 so as to be distributed over the conical surface of the plate. In' order` to `facilitate the even dis'- tribution of the oil at all points around'the conical plate lprovide a channel at `13 just vl`2within the circular notched flange 11 .so that Speccatbn of Letters Patent.

and this flange is provided with a 1919. Serial N0. 298.438.

the oil will run around along this channel and will overflow through the distributer notches or openings 12. This will prevent oil being supplied in greater quantity to one part of the conical surface than to another part because this channel lwill provide a circular conduit for the distribution of the oil immediately within the notched flange. A cap member 14: is arranged over the notched flange so as to bear thereon and form a restricted space between its lower face and the conical face of the distributor plate and this cap member is concaved on its lower face so as to conform substantially to the conical surface of the distributer plate and thus prov` lc a space for the distribution and vaporizing of the oil in a comparatively thin sheet extending uniformly around the sides of the conical distributer member. rl`his cap member is carried by a pipe 15 eX- tending down through the pipe 16 which eX- tends through the top of the arms 3 and down to a point near theilaring discharge. mouth -1 of said arms. rlhe pipe 16 provides an auxiliary air supply and Awater is introduced tl'irough the pipe 15 and is delivered to the openings 17 extending from the center of the cap member outwardly and downwardly so as to direct the steam generated from the water to points just within the annular iiange 11 so that combustion will be promoted at this point. The conical distributer plate is free from contact with the base 1 excepting at its center so that heat by conduction will not be lost or drawn from the distributer plate except to the minimum degree, this being due to the fact that the distributer plate has but a 'small connection at its central portion with the base plate whereas its dish'ed flange or flanged portion is free from connection with any adjacent partl which would act to conduct the heat away.

lt will be noticed that the upper surface of the cap member 14 is of general conical shape with its apex directed upwardly vand that this conical surface is surrounded by the flared wall of the'air discharge mouth or portion 4. The oil delivered to the restricted space betweenthe conical distributer plate 7 and he cap 14 will be vaporized and the air issuing from the flaring mouth 4f downwardly and outwardly at the edge of lthe Acap 1t and consfquycntly at the edge of the restricted vaporizing space will exert its force upon the fuel issuing' under 'the edge rat-tenten new. s, ieee.y

bearing of the cap 14 and will mingle therewith in a thorough manner.

` lt will be noticed from Fig. 8 that the air pipes 3 taper from their sides Vto the center 'of the. burner where the downwardly and I.` outwardly flared discharge mouth 4 is lo- "eated and these pipes present broad inner surfaces near their lower ends against which the llame or heat from the distributer plate impinges so that the air passing through these pipes will be heated before reaching the discharge mouth 4.-. Further it will be noticed that the dished form of distributer plate insures complete combustion of the oil as any oil which may pass unignit'ed from the edge of the cap plate will be retained by the dished portionlong enough to be subjected to the heat and llame and coinrningled with the air so 'that perfect combustion will be afforded.

At 18 I show a plate which may be formed integral with the hollow arms at the top thereoi and extending horizontally from said arms. This plate will have a confining effect on the heat andv Haine and 'will distribute the llame for the best heating effects.

lt will be noticed that the air outlet 4 flares outwardly and downwardly and its wall. is convergent in relation to the upper inclined surface ot the spreader 14 which is located substantially within this outlet. By this the air inipinging upon the upper surface of the spreader is delected outwardly and downwardly under pressure of the. large volume of air behind it so that it is discharged with force through the tapered annular outlet formed between the inclined upper surface ot the spreader and the fiariaaawe ingwall of the outlet and this air is disspreader forming a narrow space between itself and the conical distributer for the discharge of the oil laterally in a thin sheet,

air supply ineans having a downwardly directed flared discharge portion encircling the upper portion of the spreader, the wall of said dared portion being disposed in prox*- imity and at an acute angle to the distrihuter for causing a current of air to impinge upon the thin film of oil as it issues from beneath the spreader.

2. In combination in a .burner7 a conical distributor having an upwardly directed oil conduit at its center, an overlying spreader forming a narrow space between itselil and the conical distributer for the discharge of the oil laterally in a thin sheet, air supplying means having an outlet directed downwardly upon the upper side of the spreader, said spreaderdeiiecting the air downwardly and outwardly upon the thin sheet of oil on the distributer after said oil issues from` under the edgeio the overlying spreader',r the upper surface of the spreader inch-ning downwardly and the wall of the air outlet being flared outwardly and downwardly and reaching to a plane near the plane in A which the edge ofthe spreader lies, substantially as described. r i
